I have a 530 snow blade mounted on my one 14.They go ahead of the bumper just like the 10,and 12.They have a different guide mounted to the front bumper than the 10,and 12.On the 1200 I bought last year it came with a blade with no numbers on it.I havn't mounted that blade yet but it resembles the 620 blade.That blade doesn't have the guide on the front though.
